LOADING Application filed July 7,

To all whom it may concern Be it known that T, AUGUST J. HINZ, citizen of the United States. residing at l/Vo'od Lake, in the county of Yellow Medicine and State of Minnesota, have invented certain new and useful Improvements in Loading liiachines, of which the following is a specification.

This invention relates to improvements in loading machines especially adapted for loading manure though not necessarily restricted to such use.

- An important object of this invention is to provide a loading machine having novel means whereby material may be readily and conveniently picked up and supplied to the conveyer which elevates and discharges the same into a. wagon.

A further object of this invention is to provide a loading machine having a shovel or pick-up device provided with automatic means whereby the same is dumped upon reaching the limit of its upward movement or upon moving to a point above the corn veyer.

The invention forming the subject matter of this application aims also to provide a loading machine having automatic means for stopping the shovel or pick-up device when the same reaches the limit of its upward movement. v

A further object of the invention is to provide a loading machine which is simple to operate, and efficient and durable in use.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application and in which like numerals are employed todesignate like parts throughout the same,

which is mounted upon wheels 11 so that the same may be conveyed from place to place by a tractor or by horse power. Standards 12, 13 and 14, preferably of U-shaped formation are mounted upon the base 10 and form a means for supporting a conveyer 15 in an inclined position. The conveyer 15, fwhich may be of standardconstruction, comprises the usual frame about which an apron 16 extends. The apron, of course, is endless "and is composed of a plurality of strips connected in any well known manner so that the same may pass about the rollers 19 and the ends of the'conveyer. As illustrated in Figure 1, an engine 20 is mounted 'on the base 10' and is provided with a power transmitting wheel 22 having connection with a second wheel 24 through the medium of a belt The wheel 24 which is disposed beneath the conveyer, has connection with the upper roller 19 of the apron by means of sorocket wheels 20 and 21 andby a con necting sprocket chain 23. In this manner the power of the engine is transmitted to the apron 16so that when the engine is running the apron will be passed. over the rollers, though, if desired, a clutch may be interposed between the driving connection of the engine and the apron.

The means employed for dumping the material onto the apron comprises a shovel 30 which is L-shaped in side elevation and which comprises a plurality of spaced parallel forks. The shovel 30 is formed with a pair of forwardly extending spaced parallel arms 32 having elongated slots 33 within which rollers 34 operate. The rollers 34 which operatecin the elongated slots 33 have connection with a cross head 35 which, in turn, is connected intermediate its ends to a cable 36 through the medium of a clevis 37 and a pulley .38. The cable 36 is anchored at one end to the Ushaped lifter 39 having its sides horizontally pivoted as indicated at M0 to upstanding extensions ll secured to the lower portion of the elevator. The U- shaped lifter 39, which is movable over the conveyer, is adapted to be elevated for positioning the shovel 30 above the apron so that the'material carried by the shovel may be discharged onto the apron. The cable 36 which has connection with the connecting portion of the U-shaped lifter, is wound about a drum el-O rotatably carried by the standard 12 and operated from the engine by a means to be more fully hereinafter described. When the drum is operated in an anti-clockwise direction, as indicated by the arrow in Figure 2, the cable will draw the shovel 80 in the direction-of the con veyer and when the shovel reaches the limit of its movement along the ground, the pressure or pull on the cable causes the lifter 39 to be elevated with the result that the shovel is raised.

i W hen the shovel reaches the limit of its upward movement, the sides of the lifter engage a stop element 43 carried by the extension'41 and which serves as a means for limiting the forward movement of the litter and consequently the shovel.

The cable 36 is guided onto the drum 40 by a pair of pulleys 44 which are carried by carriage 45,

The carriage is, in turn, mounted on a screw threaded bar 46 extending. in spaced parallel relation to the drum and in advance of the same. The

screw threaded bar 46 is, of. course, rotated during the operation 01" the machine so that the carriage is moved transversely of the apparatus for properly feeding the cable 36 onto'the drum.

- Themeans employed for transmitting a rotary motion to the drum 40 comprises a combined clutch and sprocket wheel 50 havof teeth 51 which are lng an annular series engaged by a sprocket chaln 52 having connection with the power transmitting wheel 24 through the medium of a small sprocket wheel 58, As illustrated in detail in Figure 4, the clutch section 50 is rotatably mounted on a shaft 55 of the drum 40 and is formed with a socket which receives the male'section 56 of the clutch. The section 56 comprises a hub 57 to which a plurality of contact members 58 are connected. The hub 57 of the male section 56 is slidably and non-rotatably arranged on the .shalt be broken if desired.

55, so that when the clutch section 56 is moved into engagement with the section 50 a driving connection will be provided between the sprocket chain 52 and the drum 40. The male section 56 is formed with an annular collar 60 within which the arms or": a dog 61 are arranged. The dog 61 has pivotal connection with a. vertically arranged lever 62 adapted to be operated for moving the male section 56 along the shaft 55 whereby the driving connection between the sprocket chain 52 and the drum 40 may The upper end portion of the lever 62 is suspended from a laterally projecting bracket 63 carried by slidably receives a bolt65 carried by the lower portion of the standard 12. In this manner, the lower portion of the lever is not allowed to sway laterally or partake of unnecessary movement during the operation of the machine.

As the litter 39 is elevated, the same engages the longitudinally movable releasing rod 68 carried by brackets 69 and 70 secured to the standard 12. The longitudinally movable rod is square in cross section so that the same will not be allowed to rotate while partaking of a longitudinal movement. One end portion of the tripping or releasing rod 68 is forked as indicated at 71 and is disposed in the path of travel of the lifter so that as the lifter is elevated" the rod will be moved rearwardly. The longitudinal movement thus imparted to the releasing rod 68 forces thewedge 'jacent side of the standard 12'and the lower portion of the lever 62, so that the lever is caused to partake of a pivotal movement. This pivotal movement thus imparted to the lever causes the male section 56 of the clutch to be released from the section 50 so that the driving connection between the engine and the drum is broken when the lifter reaches thelimit of its upward movement.

A beam 7 5 extends longitudinally of the machine at a point spaced above the conveyer'and is provided with a pulley 7 6 over which a cable77 is passed. The cable'77 has its ends wrappedin opposite directions about a drum 78 so that when the drum rotates oneend portion of the cable will be wound upon the drum and the other end portion of the cable will be released from the drum. The end portions of the cable are guided onto-the drum by pulleys 80 which are mounted upon carriages 82 which correspond in construction and purpose to the carriages 45. The carriages 82 are mounted on a screw'threaded bar 83 which serves as a means of seating the carriages as the pulleys rotate. v

As illustrated in Figure 2, the drum 78 is provided at one end with a pulley 84 which is connected to a pulley 85, operated by the motor 26, through the medium of a belt 86. The rotation thus imparted to the drum 7 8 is imparted to the screw threaded bar by means'of a sprocket chain 87 which passes over sprocket wheels mounted on the shaft of the drum 78 and on the screw threaded bar 83. The carriages 8.2 are prevented from rotating by reason oi? the fact that the same have sliding contact with cross member 88 carried by the standard 13.

The cable 77 carries a flexible element 90 which is provided at its lower end with a hook 91 adaptedfor engaging the shovel 30. As the cable 77 par-takes of a movement in a direction indicated by the arrow in Figure 1, the cable 90 partakes of a like movement with the result that the shovel is returned a clutch 94 connected with the drum 7 8. The

clutch 94 may be operated by means of a depending lever 95.

In order to allow the shovel 30 to be adjusted for picking up an entire pile of material, the beam is pivoted to the standard 14 as indicated at 97 and has its forward portion supported by a plurality of standards 98.

The apparatus is positioned with. the lower end of the conveyer near the material so that as the shovel is operated, the material will be discharged onto the conveyer. Of course, a wagon or other vehicle is arranged beneath the discharge end of the conveyor so that the material will be collected upon being discharged into the same.

When the engine is started, the power will be transmitted to the several drums and to the rollers so that all will operate practically simultaneously. The rotation of the drum 40 results in movement of the shovel through the material and in the subsequent elevation of the lifter 39. The elevation of the lifter 39 results in dumping of the material from the shovel onto the conveyer with the result that the material is elevated and dumped into the wagon. When the lifter 39 reaches the limit of its upward movement, the same engages the longitudinally movable tripping device so that the driving connection between the engine and the drum 40 is automatically released, stopping the pull on the lifter. As the cable 77 is brought into operation, the hook 91 of the depending cable 90 will engage the shovel and return the same to the position illustrated in Figure 1. The motor is, of course, provided with means whereby the direction of rotation of the drum may be reversed.

Attention is invited to the fact that when with a minimum of effort and inconvenience on the part of the operator.

It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same and such minor changes in arrangement and construction of parts may be made as will remain within the spirit of the invention and the scope of what is claimed.
